> The {{Slf4jReporter}} uses a StringBuilder to generate the report that is later logged. Currently we don't pass the initial size, which for large deployments can result in frequent resizing of the backing array.
> We could either estimate the expected size based on the # of metrics, or store the size of the last report (given that the total metrics space is fairly constant).
